The Mod Squad Line Drive System Control Center is a purely passive stereo switching unit with a volume and balance control, five line inputs, and additional facilities for two tape decks. It allows the audiophile to replace a preamp, with its active gain stagesand resulting colorationwith a device that introduces no distortion or coloration other than that in the wiring, switches, and controls.

One of the nicest features of the High End is its diversity. Regardless of whatever trend is fashionable, there will always be manufacturers to buck it, and sell alternative concepts and sounds. VMPS is just such a case. With few exceptions, the recent trend in speaker systems has been toward small-to-medium-sized "monitors" with good imaging and high resolution, but limited bass and dynamics (footnote 1). The VMPS SuperTowers provide the former, but buck the trend by adding reproduction of the deepest bass and outstanding full-range dynamics.

The Oracle Delphi Mk.II ($1250) is both a turntable and work of art. It is a visually stunning product, retaining a level of styling that, in my view, has never been equalled by any other audio component. It also adds enough sonic improvements to the original Delphi that it ranks close to the VPI HW-19, and is superior, in naturalness of sound quality, to the SOTA Star Sapphire.

Some readers may feel that it is pushing poetic license beyond reasonable limits to call the Krell KSA-50 a "new-wave" amplifier. It has, after all, been around for several years. The Krell KSA-50 is new-wave enough, however, to be an incredibly stiff class-A design, rather than a pseudo–class-A circuit, and its 50 watts per channel are supported by enough of a power supply to drive an arc welder. You get about 70 watts of RMS power with 8 ohms, 150 watts with 4 ohms, and sufficient watts into 2 ohms to threaten my load resistors. There is almost enough power to drive a pair of Apogee Scintillas at their ohm setting—though I'd prefer at least the Krell KSA-100.

The latest edition of Audio's annual equipment directory lists 238 speaker manufacturers. At best I can claim to have heard one product from 10–15% of the manufacturers on this list, and the top of the current product line from a far smaller percentage.

High-quality, low-cost loudspeaker systems are not an everyday blessing. The Rogers LS3/5a has survived for more than a decade precisely because so few US manufacturers sought musical accuracy as distinguished from high output and powerful bass. The economics of loudspeaker manufacture also don't lend themselves to economy. The cost of woodwork is driving the price of speakers up almost as fast as the cost of sheet-metal work is escalating the price of electronics.

It takes more than passing courage to make another assault on building the world's best tube preamplifier. You face stiff competition from well-established firms like Audio Research, Conrad Johnson, and Counterpoint. Such units can't be made inexpensively, and you face the steadily growing problem of tube supply: it is getting harder and harder to get tubes that are stable, have predictable sound and performance characteristics, and are long-lived. And you have to show audiophiles who have been burned before that you will still be around when they need service.

Whenever I think of cone speaker systems, I think of three brand names: Snell, Thiel, and Vandersteen. There are many good loudspeakers and many good designers and manufacturers, but it is these three who, in my opinion, consistently produce the best cone loudspeaker systems. All three companies produce full-range systems, transparent systems, and systems which mate well with a wide range of equipment. Their systems can be owned and enjoyed for years. Long after some fad or special feature has given a competing designer brief notoriety, these are the products you turn back to for music.

Several issues back, I mentioned a major "new wave" of power amplifiers coming along: the Adcom 555, the New York Audio Labs transistor-tube hybrids, and the latest Krells, for example. They demonstrate that major audible improvements are still possible in something as well-explored as the power amplifier. Not only that, some of these products demonstrate that superior performance can be combined with relatively low price.
